3 Claims. 1

The present invention relates to a plumbing apparatus and has for one ofits objects the provision of apparatus for facilitating greatly theaccurate positioning and holding of an anchoring member or ring inrelationship to associated soil pipe.

In connection with the installation of plumbing fixtures such as toiletbowls in new buildings, it is desirable that the fixture holding memberbe accurately positioned with respect to its associated soil pipe sothat the fixture may be anchored without diificulties. The fixtureholding member is usually embedded in concrete, but in the process ofpouring the concrete or when the concrete is in the process ofhardening, the fixture holding member is oftentimes unintentionallymoved from its correct position and consequently, difficulties are laterencountered when an attempt is made to mount the plumbing fixture on itsholding member.

.It is, therefore, an object of the present invention to provideimproved apparatus for maintaining a fixture holding member in placewhile it is being anchored in place. Another object of the .presentinvention is to provide an improved tool for maintaining a plumbingfixture holder in place while it is being anchored, the tool beingcharacterized by its simplicity and ease of application to existingstructures.

The features of the present invention which are believed to be novel areset forth with particularity in the appended claims. This inventionitself, both as to .its organization and manner of operation, togetherwith further objects and advantages thereof, may be best understood byreference to the following description'taken in connection with theaccompanying drawings-in which:

Figure l 'is a view in elevation and partly in section of an assembly ofapparatus incorporating the present invention;

Figure 2 is a perspective view of a tool shown in Figure l embodying thepresent invention associated with a plumbing fixture holding member;

Figure 3 is a sectional view taken substantially on line 33 of Figure 1.

In accordance with the present invention the plumbing fixture holdingmember in this particular embodiment of the present invention isaccurately maintained in adjusted position with respect to the soil pipeII in the process of anchoring such member It) in concrete I2, theconcrete 12 being poured around the member Ill and then allowed toharden.

During the pouringand hardening periods the ring [-0 is firmly held inplace on an inverted U- shaped strap [4 having ears l5, l6 integrallyformed therewith which in turn have integrally formed therewithrespectively downwardly extending cylindrical spacers ll, [8.

Bolt and nut assemblies 22, 23 (which arelater used to fasten theplumbing fixture itself) serve to clamp the flange 2| of the ring shapedmember it against the spacers l1, It, the bolt portions of theseassemblies 22, '23 respectively passing through the elongated slots I9,'20, the spacers,

18 and apertures in ears 1'5, 16. The por-tion'of mainly, 1) to supportstrap [4 and ring-shaped member I'll attached thereto; and (2) toprovide .a fluid tight conduit and connection with the soil pipe II sothat. the soil pipe H andits connections with other soil .pipe (notshown) .may be suitably tested by applying thereto fluid under .pressurewhich enters through the valve 39 and passes downwardly through thecentral pipe into the soil pipe.

Resilient annular ring 32 abuts the inner sur- .face of pipe II andmaintains a fluid tight connection therebetween, this connection beingmaintained by maintaining a mechanical pressure between the oppositeedges of member 32. This mechanical pressure'is applied by the bearingmembers 28, 35 which serve as clamping members,'member '28 beingslidably mounted on pipe 3| and member 35 beingscrew threaded on pipe 3|such that by turningnut 21 in the proper direction members 28, 35 aredrawn together thereby to squeeze the annular resilient ring member 32into abutment with the innerwall of the soilpipe.

Thus, when the test plug 25 is clamped-into position for testing, thestrap l4 issimultaneously clamped into position. Further, the nature ofthe connection between the test plug and the soil pipe allows adjustmentof the position of the supported ring shaped member ID. Usuallyth'emember Ill is positioned so that the underside of the flange 2| is flushwith the proposed floor which is subsequently produced by the concrete.

It is noted that the nature of the structure is such that concreteduring the pouring operation is precluded from entering the soil pipe.

After the concrete has been poured and hardened the wing nut 21 isloosened thereby to unclamp the strap I4 inwhich case the strap 14 maybe removed after taking off the nuts on the assemblies 22, 23. The testplug 25 is completely removed and the ring and bolts extending therefromare in readiness for the anchoring of the plumbing fixture.

In the process of fastening the plumbing fixture to the ring 10,material such as oakum and a lead ring is disposed within the annularspace 40 in accordance with conventional practice.

While the particular embodiments of the present invention have beenshown and described, it will be obvious to those skilled in the art thatchanges and modifications may be made without departing from thisinvention in its broader aspects and, therefore, the aim in the appendedclaims is to cover all such changes and modifications as fall within thetrue spirit and scope of this invention.

I claim:

1. In an arrangement for accurately assembling a plumbing fixturefastening member in aligned fixed encircling position with respect to asoil pipe, the combination comprising, a device selfsupported solely byits engagement with the interior wall of said soil pipe, said devicecomprising a threaded open ended pipe extending centrally in said soilpipe, a radially expansible circular gasket encircling said pipe andengaging the interior wall of said soil pipe to secure the device tosaid interior wall of the soil pipe, a pair of clamping members onopposite sides of said gasket and mounted on said pipe, a nut threadedon said pipe and arranged to move said clamping members towards oneanother to squeeze saidgasket radially outwardly into engagement withthe interior wall of said soil pipe, a-laterally extending strap memberhaving an intermediate slotted portion encircling said pipe, saidslotted portion being clamped'between said nut and one I to the saidinternal wall of the soil pipe, a pair of clamping members engagingopposite circular edges of said annular gasket, one ,of said clampingmembers being affixed to the lower end of said pipe, the other one ofsaid clamping members being slidably mounted on said pipe, a nutthreaded on said threaded pipe adjacent to said other clamping memberand arranged to pro- I duce relative movement between said clampingended elongated slotted portion in the central region, said slottedportion extending generally transversely of the longitudinal axis ofsaid strap member, a pair of ears formed integrally with said strapmember and extending longitudinally thereof, each of said ears beingapertured, a pair of bolts each having their shanks extending through acorresponding one of said ear apertures, a tubular spacer mounted oneach of said bolts between said ears and thecorresponding bolt head, anda fastening nut threaded on each bolt in a position to clamp thecorresponding spacer between the corresponding ear and correspondingbolt head, each of said bolts being of such diameter to allow theirpassage through corresponding open ended slots in said fixture memberwhereby said fixture member may be clamped between said spacers and saidbolt heads.
